SPECIFICATION forming part of Letters Patent No. 729,857, dated June 2, 1903.

Application filed July 9, 1902. Seria1No.1l4,855. (N model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL S. GARVIN, a citizen of the United States, residing at Ans tin, in the county of Cook and State of'Illinois, have invented a new and useful Improvement in Incandescent-Electric-Lamp Holders, of which the following is a specification.

The object of my invention is to overcome 1o objections to the socket devices for holding incandescent electric lamps as such sockets arenowconstructed. Theobjections referred to are primarily due to the condition in the use of the sockets that the shades for the I 5 lamps must be furnished separately and are usually more or less difficult to fit, besides rendering indispensable means for fastening them in place, which means are unavoidably exposed to view and mar the appearance of the fixture, and the base of the socket, usually of-porcelain, is exposed and is more or less unsightly.

The common construction of the holder to which the aforesaid objections relate involves a white porcelain base carrying one of the terminals, a metal socket for the other terminal, into which the lamp is inserted, as by screwing it into place, the socket being surrounded by a metal sleeve liable to tarnish and insulated from the socket by an interposed sleeve of insulating material, and a nut of hard rubber screwing upon the forward end of the socket to fasten thereon the shade, which fits upon it more or less imperfectly as 5 a rule.

My improvement varies from the construction thus outlined to overcome the aforesaid objections inherent thereto in having the external sleeve and the shade, and, by prefer- 0 once, also a cap for the porcelain base formed in one piece as an integral whole of glass or other suitable insulating material which for my purpose is the equivalent of glass.

The accompanying drawing shows, by a 4 5 view in vertical sectional elevation, an incandescent-electric-lamp holder constructed in accordance with my improvement and depending from its support.

A isthe porcelain base at which the holder is fastened to a Wall, ceiling, or other support B and through which the current-conducting insulated wires 10 and w are led in the usual or any suitable manner to terminals in a metal socket C, shown screw-threaded, as it preferably is, and, as it may be, both internally and externally.

D is the sleeve surrounding the socket and having formed integral with it a shade E of any desired pattern and a cap F, covering the base A, the shade, the cap, and the inter- 6o mediate sleeve being formed of opaque glass of any desired color or contrasting colors for purposes of ornamentation.

By my improvement thus described I attain' not only the advantage of overcoming the objections referred to, but the construction of the fixture is materially simplified by dispensing with any nut or other fastening for the external sleeve and with an insulating-sleeve between the socket and external sleeve, and my improvement renders more easy than former constructions the matter of adjusting the fixture in place, besides enhancing its adaptability in difierent' situations for ornamental purposes.

What I claim as new, and desire to secure by Letters Patent, is-

1. An incandescent-electric-lamp holder comprising, in combination, a metal socket, contacts to which the conducting-Wires lead, and a combined shade, socket-covering sleeve and cap formed of glass in one piece, substantially as described.

2. An incandescentelectric-lamp holder comprising, in combination, a base, a metal socket, contacts to which the conducting wires lead, and a combined shade, sleeve and cap formed of glass in one piece, the sleeve covering said socket and the cap covering said base, substantially as and for thempur- 9o pose set forth.
